Specification of Letters Patent.

Patented July 14, 1908.

To all 'whom it may concern:

Be it known that we, GEORGE L. WALL, residing at 1103 l West Highstreet, Lima, county of Allen, and State of Ohio, and LEWIS E.FEIGHTNER, residing at 715 South Broadway, Lima, county of Allen, andState of Ohio, both citizens of the United States, have invented certainnew and useful Improvements in Locomotives, fully described andrepresented in the following specification and the accompanyingdrawings, forming a part of the same.

` The object of this invention is to furnish a means of whollysupporting a locomotive frame upon more than two pivoted trucks, so asto distributethe weight upon a large number of journals, and thus permita locomotive of great weight to be sustained wholly upon truck-wheelswhich can follow a curved track independently.

In the present invention, swing-bolsters i are pivoted beneath the twoends of the locomotive frame, and the ends of both swingbolsters aresupported upon separate trucks.

By thisv invention, four pivoted trucks can be used, two under each endof the locomotive frame, the center of the swing-holsters at each end ofthe locomotive being pivoted beneath a body-bolster connecting thesideframes of the locomotive. Only two swingbolsters are required, andthe whole locomotive is thus supported upon two centerplates; whichleaves all vthe trucks free to turn in any degree required by thecurvature of the track, and enables each of the truckwheels to followthe track independently. The ilanges of the wheels may therefore beiitted properly to the rails, and may operate most effectively inguiding the locomotive,

which is of especial importance in a structure having a long wheel-base.

It is readily seen in the drawing, that the truck-bolsters are divergentfrom one another, as is necessary in turning curves; which is effectedby a free connection with the ends of the swing-bolster.

The body-bolster is rovided with a center-plate to rest upon t eswing-bolster; and

each swing-bolster has center-plates under its vopposite ends to rest uon the truckbolsters; and all of the trucs are thus enabled to turnindependently, and their wheels are enabled to follow the track-rails inturning curves. A locomotive having the -called Shay locomotive, inwhich vertical engines at the side of the boiler fireboX are used topropel a horizontal crank-shaft, and such crank-shaft connected byuniversal joints and slip-couplings with all the wheels in the differenttrucks. All of the truckwheels may thus operate as drivers, and all ofthe driving-wheels be furnished with flanges to hold them in place onthe rails.

The trucks are shown herein provided with two axles and four wheelseach, thus su porting the locomotive u. on sixteen wheelis); but moreaxles and whee s may be used in each truck, if desired. i

In the annexed drawing, Figure 1 is a side elevation of a locomotiveprovided with the improvements; Fig. 2 is a plan of the four trucks withthe swing-holsters resting thereon,` and the crank-shaft with itsconnections to the truck-wheels. The locomotive frames are alsoindicated by dotted lines. Fig. 3 is a plan of the swing-bolster; Fi 4 aside view of the same; Fig. 5 a vertica section of the bolster throughthe central ivot-plate; Fig. 6 a vertical section ofthe bolter on line 66 in Fig. 3, through one of the end centerlates; Fig. '7v is a side viewof the bodybolster with cross section of the swing-bolster beneath thesame; Fig. 8 shows the under side of the bod -bolster; and Fig. 9 is aplan of the truck-bo ster and end frame. ct designates the left handlocomotive frame, and l) the right hand frame connected by cross-ties cand by the body-bolsters d which-have center-plates e to rest upon thepivot-plates f of the swing-bolsters. The swing-bolsters are shown inFigs. 3 to 6 inclusive, made with two parallel side girders g betweenthe ends of which center-plates h are also secured to engage thepivot-plates upon the truck-bolsters i.

The swing-bolster is shown at the middle with a pivot-plate f having itscircular face resented upwardly to support the bodyolster d by itscenter-plate e, and the swingbolster i's furnished at the opposite sidesof such pivot-'plate with bearing-plates or brackets k having socketsformed upon the contact with segmental seats m upon the yunder side ofthe body-bolster.

The bearing-blocks furnish a means of using harder metal for the wearingface and to compensate for wear as the blocks may be readily renewedwhen worn, and the sockets are formed simply as a shallow recess with amarginal ange 7c to hold the bearing-blocks in place. The ends of theswing-bolster at the o posite sides of the end center-plates h are a sofurnished with brackets n having bearing-plates o with their facespresented downwardly to rest upon bearing-blocks q seated in sockets rupon the top of the truckbolsters i at the opposite sides of itspivotplate. It will be noticed that the pivotplate f and brackets lc atthe center of the swing-bolster face upwardly, while the center-plates7L and the faces 0 upon its adjacent brackets project in a reversedirection.

The details of the truck construction are omitted in the drawing, asthey form no part of the present invention, but they are each showncarrying two axles s, and the wheel at one end of each axle providedwith a bevelgear t. The rebox of the steam boiler m swings between theframes, at the middle of their length, and four engine cylinders u areshown upon the side of the iirebox in Fig. l, with a crank-shaft e,having four cranks w journaled in bearings w/ which are supported uponthe locomotive frame l).

The truck-wheels are all shown ianged to tit the track-rails y of Figs.1 and 2, and each of the trucks is shown constructed, as is common inShay locomotives, with bearings carrying a driving-shaft :c havingpinions t meshing with the bevel-gears t upon the wheels of such truck.The ends of these driving-shafts and the opposite ends of thecrank-shaft e are shown provided with universal joints u which arevconnected by slipcouplings e', thus connecting the crankshafts with allof' the axles in the four trucks, and at the same time ermitting eachtruck to assume an indepen( ent position upon the track-rails y whichare shown in Fig. l.

The locomotive frames are shown in Fig. l provided with a water-tank zand a coalunker .e/ at the rear of the iirebox, and as the entire frameis carried by the swing-bolsters upon which the body-bolsters d arepivoted, the whole weight is carried by the pivot-trucks, and all of thewheels which carry such weight may be utilized as drivingwheels byconnecting them with the motive power, as shown in the drawing.

The center-plates e upon the body-bolsters d are shown in Fig. l setmuch nearer to the .frame b than the frame a, as the frame I) carriesthe engine, whose weight is balanced by thus arranging the center-platesd.

The essential feature of the invention is the supporting of thelocomotive frames with the motor upon swing-bolsters pivoted under itsopposite ends, each swing-bolster also having center-plates under itsopposite ends and trucks supporting such end eenter-plates with wheelsjournaled in said trucks, and a part at least of said wheels havingconnections with a motor to drive the locomotive.

The construction is especially adapted, as stated above, for use in aShay locomotive, in which all the supporting wheels are utilized asdriving-wheels by a ilexible gear connection with a motor-shaft, thuspermitting all the wheels to be iianged and all the trucks to turnindependently in passing over curves. It is not, however, essential tothe present invention that all of the supporting wheels should beconnected with the motor, as a art of the wheels may be used as trailingor eading wheels, if desired.

The supporting of the entire weight upon swing-bolsters and pivotedtrucks is equally a plicable to a locomotive employing an electricmotor, a gas motor, or any other niotor agent.
